Application filed. November 4, 1909. Serial No. 526,263.

To all whom 'ii'may concern:

Be it known that I, ALExUs G. Lmnonnri, of Molina, county of Rock Island, and State of Illinois, have invented a new and useful improvement in Two-Way Plows, of which the following is a specification.

This invention relates to wheel plows of the t pe in which a wheeled frame is provider with two plows pointing in the same direction but facing right and left, so that by the alternate use of the two plows,

.h t machine travelng respectively in opposite directions, all the furrows will be thrown or turned in the same direction. In other words, when one plow is in action, with the machine traveling in one direction, the furrows will be turned in the same dircotitm as those turned by the other plow, with the machine traveling in the opposite direction. By this means, the machine by being turned at the end of each furrow toward the land, will plow the entire field with the furrows in one direction, thus leaving it. level. and free from dead furrows or rid lily invention consists of various improvements in machines of this type, dirooted more particularly to the means for mounting and raising and lowering the plow beams; to the means for maintaining the machine truly in the line of draft, so that the furrows will be straight and unil'orm; to the means for guiding the machine: and to various other features (losigned to render the mechanism simple in its roustrluaiou ahd adjustments, and cilia live in operation.

in the accompax'iying drawings:-l igurc l a. side elevation of myimprovcd machine. showing the near plow lowered to throw the furrows to the right, and the other plow raised out of action. Fig. 9 is a similar view from the opposite side of the machine. Fig. is a top plan view of the machine. Fin". c

y is a rear elevation of the machine with the parts in the position of Fig. 1, certain porlions being in section and broken away. Fig. 5 is an elevation of a portion of one of the adjusting levers, showing how the sliding block carried thereby is held in engagementwith the scgmental frame, certain parts being omitted.

Referring to the drawings :-The frame of the machine consists of the arched memher 1 and thc horizontal forwardly extending U-shaped frame member 2, the sides "2" of which are firmly fixed at. their rear (llds to the vertical limbs of the arched member by means of clip-bolts 3, extending through the frame and embracing thc member limbs. At its forward end, and to our side, the frame has fixed to it a tongue 4, while at the rear, and supported over the arched member, is a drivers seat sustained by a seat spring or bracket fixed at. its lower cud to the member. The frame is supported on opposite sides by wheels (3 and 7, which are so mounted that they may be swivclcd or turned around a vcrtic; l axis to guide the machine, and may also be shifted to and fro to raise and lower the plow beams; and as the means for mounting the two wheels are the same on both sides of the machme, a de-' scription of those on one side will sutlice.

l'lach limb of the arched member is loosely encircled by a vertical collar 8 formed with a peripheral swell having: an internal groove 8" chibracinn the clip-bolt 5, whereby the collar is confined in a vertical direction on the member limb but is permitted to rock horizontally thereon around a vertical axis. Fixed to the lower end of the colla is a downwardly and outwardly inclined hea ing sleeve 9, in which mounted a st l rock-shaft 10, projecting at its inner end a short distance beyond the rod of the HlLtI'l-I and having fixed to its outer end a lowliwardly extendingbrackt plate 11, from the upper end of which extends a \i'llital band lever 12, fixedly commuted with the bracket plate. this hand lover being l'or the purple as will be presently described. of controlling the adjustments of the plow beams. .-\t its lower end. the bracket plate is formed with a sleeve 11 encircling and fixed to a horizontal dowmvardly inclined stub axle 1.3, on which is loosely mounted, at the outer side of the sleeve, the furrow wheel 7, having fixed to it adjacent to the sleeve 11, a

ratchet wheel '14, the purpose of which will presently appear. The stub axle 13 is provided' at its enner end with an upwardly extending arm or stem 15, which extends vertically in line with the vertical axis on which the collar 8 turns, the upper extremity of said arm being offset and mounted on the inner projecting end of the rock shaft 10, before alluded to. From this construction, it will be seen that the wheels (3 and 7 are carried by supports which are movable around a vertical axis passing centrally through the vertical limbs of the arched member. It will further be seen that the wheels are staggered or inclined inwardly to. adapt them to travel in the corner of the furrow and act as furrow wheels to maintain a uniform cut, one of the wheels, aswill b'e presently described, acting as a land wheel, while the other is traveling in the w furrow, and vice versa, according to the di-' rection in which the machine maybe traveling. It will further be' seen that the stub axles on which the wheels are mounted. are

pivotally connected ata point above the.

wheel axis, sothat the wheels may be swung bodily back and forth in relation to the frame on a downwardly. inclined axis coin-[i cident with the rock shafts 10, the purpose of this SWlIlglIU motion being, as will be presently described, to effect the raising and lowering of the plow beams. It will further be seen that the wheels may be turned or swiveled around a vertical axis, the purpose of this being to guide the frame without the 25.necessity of swingingthe tongue to-efiect' this object. The swiveling motion of the wheels .130 thus guide the machine is con:

controlled and effected by a transversely arranged horizontal foot lever 20, pivoted beso tween its ends on a bracket 21, fixed to the front end of the, frame member. ends of this lever are jointe ends of two bars-22 and 23, extending rearwardlyside by side with their rear ends jointed to the inner ends respectively of two horizontal transverse arms 24: and 25,. which i arms have their outer ends fixed respectively to the upper endsof thegfiwo collars 8 of the.

.wheel supports at pointsiforward of thevertical axis on which the collars turn. The

driver by rocking the lever 20 on its central axis, may, by" the connections described, turn or swivel the Wheels to the right or left, and in this manner cause the machine to track in the direction in which the wheels extending rearwardly with its rear end eX- tending loosely through slots in a U-shaped frame 20?, fixed 'to the frame of the ma- .610; chine In one edge, the rod 20' is provided 'fwith ,'aseries of notches 20, engaged by a [roller 20?, mounted between the ends of a 7 second U shaped' frame 20 which embraces I the rod and has connected with its. end, a 5,5 stem 20, extending'loosely through the end To the i V the forward 'to the frame.

ceases of the frame 20 a spring 20% encircling the stem and bearing-between the end of .the frame 20 and a tension nut 20 on the end of the' stem. As a result of this construcv tion, the spring acts to engage the roller i with yielding pressure in one :of the notches in the rod, and in this manner locks the parts frictionally-and yieldingly so as to hold the wheels in the position set by the foot lever. In operation, the locking device described, while maintaining the wheels in the position set, yet at thesame time may be readlly actuated by the driver to release them when the direction is to be changed. By reason i of the comparatively great leverage on the swiveling wheels, due to the form of the connection between them and the foot lever such connection embodying the short.leverage between the axis of the lever 20 and the a connection therewith of the bars 22 and 23, and the comparatively long leverage between the inner ends'of the arms 2e and 25 and their outer ends where they are 0on nected with the collars 8, the driver may readily release the locking device when the wheels are to be turned, andas the leverage of the wheels on the foot lever is correspondingly decrea'sed,the locking device will not .be released by the action of the .wheels, so

that, the latter will be maintained in the position set.

Two plow beams 26 and 27 are equippedv with moldboard plows 26 and 27, which point in the same direction in: the line of travel, but which are arranged with their moldboards right and left of facing in opposite directions. One of the ;)'Ll'0WS is raised out of action when the other is lowered into action with the machine traveling in one direction, and when the machine is reversed at the'end of the furrow'and travels in the opposite direction, the plow which had before been in action is raised out of action. and the other lowered, with the result that all of the furrows will be thrown in the 1 0 same direction, notwithstanding the successive reversals of the directionof travel of the machine. v

The beams are pivoted between their ends respectively to two bails 30 and 31, jointed at their adjacent ends to a hanger 32, depending froin the arched member, and ointed at their outer ends respectively to arms w 33 and 34, fixed to the side bars of the frame member and at its rear, the construction being such that the bails may be swung independently of each other and relatively,

The outer limbs of the bails are operatively connected with the swinging stub axles in such manner that w11'en g 2 these axles are shifted forwardly and 'baclc wardly with reference to the frame,-, the bails will beswung with them, and in this way will raise and lower the plow beams, as v In order that this action the case may be;

ceases chine, the vertical portions of the stub axles will turn 'in the plates around a vertical axis coincident with that of the collars 8, 8,

' but when the plows are elevated and the llt wheels are swiveled, the stub axles will shift laterally between the plates It is seen,

therefore, that while the bails will be swung simultaneously with the forward and backward motion of the wheels, the latter may at the same time be swi'veledor turned without regard to the position which the bails may be as regards their fore'and aft adjustments.

The vertical adjustmentsof the plow beams and the raising and lowering of the same are controlled by the hand levers 12, 12, before alluded to, through the medium of the mechanism now to be described; and as this mechanism is the same on both sides of the machine, a descriptidn of that on one side will suffice.

On reference to Figs. 1 and 4, it will be seen that each hand lever 12 has mounted on it a sliding block 35, provided on its lower end with an inwardly extending lug 36 adapted to coiiperate with the underside of a segmental frame 37, extending fore and aft and fixed to the collar 8, the block being held to the frame by means of an overhanging nose 35 carried by the block, and the said frame being provided at its front and rear with two sets of notches 38 and 39, in which the lug 36 is adapted to enter. The block 35 is acted on by a spring 40 connected" to it through the medium of a plate ll which is connected to the block as hereinaii end of a rod 4.2-}, which extends upwardly alongside the lever 12 and has its upper endjointcd to one arm 44 (If an elbow lever 45,

mount ed to rock on a pivot pin 1:6, extending between cars 47 on the upper end of the lever 12. The other. arm 48 of the elbow lever extends upwardly and serves as a handle for rocking the elbow lever to actuate the parts connected therewith. The elbow lever, where it encircles the pivot-pin, is slotted, and in this slot and on the pin (l6, is mounted the inner end of an arm -19, provided with a lug 50, engaging a lug 51 on the elbow lever. From this construction, it will. be seen that the spring 40 pulling up on the sliding block will act, through the connection of said block with the rod, to hold the elbow lever with its arm 48 in an upright position, and by the engagement of the lugs 50 and 51 with eacli other, will hold the pivoted arm 49 at a downward inclination. When the pivoted arm is swung upwardly, it will, by the engagement of the lugs 50 and 51 with each other, rock the elbow lever 45 downwardly, which action will in turn lower the block 35 and disengage the lug thereon from the notches in the segment frame. At the same time, the plunger all. will be projected downwardly but not sulficiently tar to extend in the path of the teeth of the ratchet Wheel 14, the motion of the plunger being limited by the pivoted arm &9 contacting with a fixed lateral handle on the upper end oi the lever 12. \Vhcn, however, the arm 4.8 is swung downwardly, it will move independently of the pivoted arm 49, and the plunger will be projected to its full extent and into engagement with the teeth of. the ratchet wheel, thereby loch- .ing the :t'urrow wheel against rotary motion.

It is seen, therefore, that by the action of the pivoted arm l9, the lever will be released from the segment frame, and by swinging the lever back and l' orth when thus released. the ground wheels may be swung back and forth and the depth of the plow in the ground controlled by the engagen'icnt of the lug in one of the rear notches in the segment frame. If, however, the plow is to be raised out oi? action, as at the end ol the 'l'urrow for turning the machine, the arm -18 of elbow lever 45 is depressed, which will first disengage the lug ill; from the segment frame, and will then project the plunger 41 downwardly between the teeth of the ratchet wheel l l, thereby locking the tin row wheel against movement, the result be ing that the forward motion oi the plow by the draft animals, with lhe lurrow wheel in contact with the ground. will draw the frame of the plow, inrliu'ling the arched member, forward relatively to the wheel, and the parts locked thereto, this relative motion being about the shaft '10 as an axis and resulting in the upward swing of the bail and the elevation of the beam and the forward motion ol the hand la er-alongside of and with reference to the segment frame. his motion of the lever will continue until a roller 53 on the sliding block rides up a stop 54:, projecting-upwardly; from the segment frame near its forward end, whereupon theslide carrying the roller will be moved upwardly .with reference to the lever, thereby withdrawing the plunger from engagement with the ratchet wheel and releasing the.

latter, and at the same time engaging the lug-3G on the slide with-one of the notches in the underside of the segment frame at the front, with the result that the lever will be held with the plow beam locked in elevated .position. It is seen, therefore, that l the elevation of the beams is effected entire y .oted arm 4C9 is swung upwardly by the hand,

by the draft of the animals, the projection of the plungers between the teeth of. the

.ratchets, acting merely to initiate ,the rais-l ing action.

In lowering the plow into action, the pivthereby disengaging the lug 36 ,from the notch in thesegment frame, and the beam f by its own weight will-swing the bail down and restore the parts. to their former lowered 1 position, the plow being locked to its proper depth in the ground by the engageme'nt.. of

the lug in one or the other of the notches at the rear end of the segment frame."

- .to approach and be within. reach of .the

driver.

It will be observed that while the'aiiles of the furrow wheels are downwardly iliclined to stagger the wheels, and .while the axis' of the shafts 10 on which the wheels swing is'similarly inclined, so'that the Wheels will maintain their staggered positions when raised or lowered,-'the levers- 12 extend in a truly vertical position from the bracket plates. .As a result, when the levers are shifted back and forth, they will move in outwardly curved paths and in close contact with the segment fram'es which are-correspondingly curved. to enable thelever to co-' operate therewith. This action causes the levers, when at their front or rear positions,

In the operation of the machine, when'it drawn" over the field in one direction, one

of the plows,; preferably that on the right, is lowered into action, and the other is raised out of action, the result being that the fur- I rows will be turned to the'right', the furrow wheelgou the right traveling in the-furrow previously made, and the, wheel on the other side 'of the machine, which is swung to the rear and consequently [somewhat elevated, traveling on-the unplowed ground. As the end of the furrow is reached, the hand lever.-

12 of the active plowislocked to its furrow wheel by the operation of the elbow lever 45,

"and the draft of the animals will el evate the active plow out of action. The driver then by the foot lever 20 turns the wheels to the left for the ma furrow, and as the machine straightens out for the: return, the driver releases the lver 12 onthe left by drawing. its pivoted arm 49 upwardly. The plow on the left is'then lowered by its weight, and its straight and uniform.

{.plow, frame and tongue all travel parallel .f-with the furrow", and the operation of the 'hand lever swings to the rear, where it is.

the end of this furrow, the active plow is .so on, the machinetu'rning toward the land@ raised, as before, and the other lowered, and

at the end of each furrow, and the-two plows acting alternately and throwing all the fur ,-rows in the same direction away from the land. It will bejobserved. that'thetwowh'eels,

constituting the sole. support of the machine, 1 act alternately as land and furrow wheels,

as the direction of the'machine is "alternately v reversed, and as the wheels are staggered, they,- by traveling in the cornersof .the furrows, cause the successive furrows to-be cut"- In the operation-of the machine, thedraft animals willsometimes-walk 'a littleto one 'side and in this manner affect the width of out. If the guide of the machine, under these conditions, is accomplished by swinging the tongue, the angle of the plows with respect to the line of the furrow must be corrected or resistedfrom the forward end of the tongue. This a'ction causes drag on and discomfort to the draft animals. By

means of my improved guiding device, the

uidi'n device to effect a chan e in .the. g a: z:

width of the cut does not'throw either plow, frame or tongue out} of a straight line with the furrow, the inclined furrow wheels tending to 'draw-the'whole plow bodily to'the; si e desired; The, machine being guided independently of the tongue, that is, by the swiveling of the wheels, enables the turns I to r bemade uniformly, positively and promptly, and without drag on or discom-,

-fort to the draft animals, asusually occ urs when the machine is turned bv the swinging of the tongue.
